Fructose intolerance is best confirmed through genetic testing. A breath test can also be conducted, which measures the concentration of hydrogen and methane in the exhaled air after ingestion of a fructose-containing substance (however, this method is less accurate). In general, the severity of intolerance depends on the level of appropriate enzyme production - intolerance can therefore be "partial," whereby a certain amount of the substance can be consumed without apparent adverse symptoms.
There are numerous types, primarily those that promote the production of digestive enzymes and juices, thereby making the entire digestion process more efficient. The most significant include cumin, coriander, lovage, pepper, fennel, ginger, and blends like curry.
